The presenter of Saturday's Virtual Grand National Nick Luck has admitted the race now has "an extra layer of significance" and will create a welcome distraction from the daily coronavirus news.
Millions are expected to watch the race on ITV this weekend - with major bookmakers donating all profits to NHS Charities Together.
Luck told the PA news agency: "It was never set up for a betting event. So it's a great tribute to everyone involved to raise money for the NHS." ITV announced plans last week to air a virtual version of the world's greatest steeplechase, using the latest CGI technology and algorithms, with the race taking place at 5.15pm, replicating the start time of the real thing.
